The new S3 bucket also receives regular uploads of large sets of files from users worldwide. When the new S3 bucket is put into production, the upload performance from certain geographic areas is lower than the upload performance that the existing S3 buckets provide. What should the SysOps administrator do to remediate this issue?

Suggested answer: B

Explanation:

https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-lock-overview.html Ingovernance mode, users can't overwrite or delete an object version or alter its lock settingsunless they have special permissions. With governance mode, you protect objects against beingdeleted by most users, but you can still grant some users permission to alter the retentionsettings or delete the object if necessary. You can also use governance mode to test retention-period settings before creating a compliance-mode retention period. In compliance mode, aprotected object version can't be overwritten or deleted by any user, including the root user inyour AWS account. When an object is locked in compliance mode, its retention mode can't bechanged, and its retention period can't be shortened. Compliance mode helps ensure that anobject version can't be overwritten or deleted for the duration of the retention period.
